Pantyliner

When evaluating pantyliners, prioritize the top sheet material, which should be non-woven cotton or bamboo fiber for breathability and skin sensitivity. The absorbent core typically uses Air-laid paper or a thin layer of SAP (Super Absorbent Polymer) to maintain a slim profile while ensuring dryness. Ensure the back sheet is a breathable PE film to prevent leakage while allowing air circulation, which is critical for preventing skin irritation.

For cross-border trade, products must meet strict safety standards. Ensure the supplier holds ISO 9001 for quality management and ISO 13485 if the product is classified as a medical device in certain regions. For the US market, FDA registration is often required, while the EU market necessitates CE marking and compliance with REACH regulations regarding chemical substances. Additionally, OEKO-TEX Standard 100 or GOTS (for organic cotton) certifications are highly valued by eco-conscious consumers.

Perform a strike-through time test to measure how quickly liquid is absorbed and a rewet test to ensure the surface remains dry under pressure. Check the adhesive strength of the back strip; it must be strong enough to stay in place during movement but leave no glue residue on the fabric. For scented or herbal versions, verify that the additives are hypoallergenic and clinically tested to avoid causing pH imbalances.

B2B buyers should inquire about customized shapes (e.g., T-shape for thongs or wide-wing designs) and thickness variations (typically 1mm to 3mm). Discuss packaging options, such as individual film wrapping versus bulk packs, and the ability to print private labels using eco-friendly inks. Many top-tier suppliers on Made-in-China.com also offer functional chips, such as anion, charcoal, or far-infrared strips, which can serve as a unique selling proposition (USP).

Always request a pre-shipment inspection (PSI) by a third-party agency like SGS or Intertek. Focus on microbiological testing (total viable count) to ensure the products are sterile and free from bacteria like E. coli or Staphylococcus aureus. Using the Secured Trading services on Made-in-China.com can also protect your payment until the goods are verified against your specifications.

Negotiate based on Total Cost of Ownership (TCO) rather than just the unit price. Ask for tiered pricing where the unit cost drops by 5-10% as volume increases beyond 500,000 units. Request that the supplier includes 1-2% extra spare units in the shipment to cover any potential packaging damage during transit, and negotiate for shorter lead times (25-30 days) for repeat orders.

Pantyliners are lightweight but high-volume (cubage). To optimize costs, use High Cube (HC) containers and ensure the outer cartons are double-walled corrugated fiberboard to prevent crushing. Since hygiene products are sensitive to moisture and odors, instruct the logistics provider to avoid storing the containers near chemicals or in high-humidity areas. Ensure the HS Code (typically 961900) is correctly declared to avoid customs delays or incorrect tariff applications.
